Be 1t known that I, JOSEPH F. LAMB, a citizen of the United States, anda resident of New Britain, in the county of'I-Iartford,

State of Connecticut, have invented certain new and useful Improvementsin Knives, of which the following is a specification This inventionrelates to new and useful generally the handle; I), the blade; 0, the

spring;and d, the blade pivot.

The handle is formed from sheet metal and when made in two parts, asshown in Figs. 1 and 2, each half of the handle is drawn up to shape sothat the drawn up edges will butt along what becomes the me dian line ofthe handle when seen in edge view. These two parts are convenientlysecured together at one end by the pivot pin (Z; at the other end by apin 6. In order to give the effect of a full bolster at the blade endthe full width of the handle may be carried out as indicated in Fig. 2;and to supply a proper bearingfor the blade, washers 5, 5, may bepositioned insideof the handle at opposite sides of the blade tang.

The spring is ofthe novel form shown in the drawings and of a typewhich'does not require any drilling to receive a rivet for, holding itin place. I The outer end of'the spring is curved as at 9, to' be seatedwithin the end of the handle and interlocked with the pin 6. It isshouldered at an interme-' Specification of Letters Patent.

tions and Without the necessity of an eX- 'penslve and delicate drillingand riveting operation such as is customary in the ordinary knives.

The two handle members may be assembled together and the springintroduced 7 I afterward by passing its curved end back of the rivet 6,after which the blade tang can be positioned and riveted intoplace.rivet 6, would prevent any tendency of the spring to shift toward theblade end of the handle, although there is small liability of any suchmovement. I

. Handle blank of Fig. 3 is designed to produce a one-piece handle, theflanges 15, being bent over to close the end of the handle and, whenproperly shaped and folded together, the complete either the spring orthe blade is installed.

In accordance with the provision of the patent statutes I have describedthe princi- .ple of operation of my invention, together withthe'apparatus which I now consider to represent the best embodimentthereof; but I desire to have it understood that the ap aratus shown isonly illustrative, and tiiat the invention can be carried out by othermeans.

I claim as my invention A knife comprising a handle of uniform thicknessthroughout substantially itsentire length, formed from a blank of sheetmetal and having a back with a slot at its forward end, and cuppedsidesthe edges. at the rear ends of which are curved and abut to form acurved closed rear end on the handle; a pin adjacent the rear curved endof the handle for securing the sides thereof together; a

spring in the handle having a shoulder fit ting against the end of theslot in the back thereof, said spring having its rear end curvedsimilarly to and seated in the curved end of said handle andinterlocking with said pin; a blade having a tang positioned between theforward ends of the sides of the handle and bearing against the innerface of said spring; a solid, non-yieldable washer on each side of saidtang and within the recesses of the cupped sides'of said handle, and a,pin extending through the sides of said handle, washers and tang forholding the parts in assembled position.
